How do I identify a race condition in my code?

You can identify race conditions by using the race detector. It will report data races when you run your program.

Can you give an example of a deadlock?

Sure! A deadlock occurs when two goroutines are waiting for each other to release resources. For example, if Goroutine A locks Resource 1 and waits for Resource 2, while Goroutine B locks Resource 2 and waits for Resource 1.

What tools can help me visualize concurrency in Go?

You can use the Go tool pprof for profiling and visualization, or go trace to get a detailed view of goroutine execution.
